Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to a bolt pre-drying machine before hot-dip galvanizing. Background Technology

[0002] Hot-dip galvanizing, also known as hot-dip zinc plating, is an effective method of metal corrosion protection, primarily used in metal structures across various industries. The hot-dip galvanizing process involves immersing rust-removed steel components in molten zinc at approximately 500°C, causing a zinc layer to adhere to the surface of the steel components, thus achieving corrosion protection. Before hot-dip galvanizing bolts, a drying machine is used. This machine utilizes heat energy to reduce the moisture content of materials, performing drying operations on objects. The dryer heats the material to vaporize and remove moisture (generally water or other volatile liquid components), obtaining a solid material with a specified moisture content.

[0003] An existing patent (publication number: CN203364561U) discloses a pre-drying machine for hot-dip galvanizing bolts, which uses a steam radiator. First, evaporation absorbs heat for primary heat dissipation. Then, the steam, through the radiator, generates hot air that comes into contact with the workpiece for secondary heat dissipation. This results in uniform heating of the wet material, strong drying capacity, simple structure, and low drying cost. However, in implementing this solution, the following problems were found in the existing technology, which have not been adequately resolved:

[0004] The device uses a conveyor belt to dry bolts during operation. However, the bolts tend to pile up during transportation, resulting in limited working effect for some bolts and affecting subsequent galvanizing work. Manually laying the bolts flat can easily damage the hands. Utility Model Content

[0005] To address the aforementioned issues of bolts accumulating and affecting drying efficiency, and the cumbersome process of flattening bolts, this invention provides a bolt pre-drying machine for hot-dip galvanizing.

[0006] This utility model provides a bolt pre-drying machine for hot-dip galvanizing, which adopts the following technical solution:

[0007] A bolt hot-dip galvanizing pre-drying machine includes a main body and a drying mechanism. A heat insulation cover is connected to the top of the main body. An electric push rod is installed inside the heat insulation cover. An adsorption magnet is connected to the bottom of the electric push rod. Linkage blocks are connected to both sides of the adsorption magnet. An iron filter screen is installed below the adsorption magnet.

[0008] A connecting block is connected to the lower part of the heat insulation cover, a side plate is connected to the lower part of the connecting block, a first roller is connected to the center of the side plate, an extension block is connected to the left side of the connecting block, a top plate is connected to one side of the extension block, a rotating rod is connected to the lower part of the top plate, and a second roller is connected to the lower part of the rotating rod.

[0009] The above technical solution facilitates the use of adsorption magnets and iron filters to continuously attract and remove bolts, achieving the purpose of flipping them over and improving the drying effect. Furthermore, by setting a first roller and a second roller at the feed inlet to separate the bolts, the drying effect of the bolts is guaranteed.

[0010] Optionally, in the above-mentioned bolt hot-dip galvanizing pre-drying machine, the drying mechanism consists of a front drying chamber, an airflow channel, a blower, and a rear drying chamber, and radiators are installed inside the front drying chamber and the rear drying chamber, and the blower is located at the center of the drying mechanism.

[0011] The above technical solution facilitates the drying of bolts through a drying mechanism, ensuring the drying process is carried out.

[0012] Optionally, in the above-mentioned bolt hot-dip galvanizing pre-drying machine, the linkage blocks are symmetrically distributed on both sides of the center of the adsorption magnet, the linkage blocks and the adsorption magnet are installed as an integral unit, and the adsorption magnet and the electric push rod form an integrated lifting structure.

[0013] The above technical solution facilitates the interaction between the linkage block and the adsorption magnet, allowing the adsorption magnet to move up and down, ensuring the subsequent bolt flipping operation.

[0014] Optionally, in the above-mentioned bolt hot-dip galvanizing pre-drying machine, the adsorption magnets are evenly and equidistantly distributed above the iron filter screen, the iron filter screen is integrally installed with the heat insulation cover, and the width of the iron filter screen is consistent with the width of the inner wall of the heat insulation cover.

[0015] The above technical solution facilitates the adsorption of bolts through an iron filter screen. When the adsorption stops, the bolts fall and flip over, thus achieving the purpose of bolt flipping.

[0016] Optionally, in the above-mentioned bolt hot-dip galvanizing pre-drying machine, side plates are symmetrically distributed on both sides of the extension block, and the side plates form a rotating structure with the first roller through a rotating rod. The extension block and the heat insulation cover are installed as an integral unit.

[0017] The above technical solution facilitates the use of the extension block and the side plate to allow the rotating rod to drive the first roller to rotate, thus flattening the bolts.

[0018] Optionally, in the above-mentioned bolt hot-dip galvanizing pre-drying machine, the extension blocks are evenly and equidistantly distributed on the left side of the connecting block, the extension blocks are connected to the side plate by hot-melt connection, and the side plate forms a rotating structure with the second roller through a rotating rod.

[0019] The above technical solution facilitates the distribution of bolts by using the side plate in conjunction with the second roller, thus preventing bolts from accumulating in one place.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] By setting an iron filter screen and an adsorption magnet above the main body of the device, the adsorption magnet imparts magnetism to the iron filter screen during the drying process, thereby attracting its bolts. After the adsorption magnet detaches, the bolts below the iron filter screen fall off, thus achieving the purpose of automatic flipping, ensuring the drying effect. In addition, the iron filter screen has a hollow structure to prevent it from affecting the drying process.

[0022] By setting a second roller on the left side of the heat insulation cover to cooperate with the first roller, the second roller separates the bolts in multiple places, avoiding a large number of bolts from accumulating in one place. At the same time, the distance between the first roller and the main body of the device is limited, preventing multiple bolts from stacking into the heat insulation cover, thus improving the drying effect.

[0028] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1-4This utility model provides an embodiment of a bolt pre-drying machine for hot-dip galvanizing, comprising a main body 1 and a drying mechanism 2. A heat insulation cover 3 is connected to the top of the main body 1 to ensure the drying process. An electric push rod 7 is installed inside the heat insulation cover 3 to automatically raise and lower the adsorption magnet 5, ensuring automatic flipping. The adsorption magnet 5 is connected to the bottom of the electric push rod 7, and linkage blocks 4 are connected to both sides of the adsorption magnet 5. An iron filter screen 6 is installed below the adsorption magnet 5 to adsorb and ensure that multiple bolts are flipped.

[0030] A connecting block 8 is connected to the lower part of the heat insulation cover 3, and a side plate 12 is connected to the lower part of the connecting block 8. The side plate 12 limits the first roller 10 to ensure its stable rotation. The first roller 10 is connected to the center of the side plate 12. An extension block 9 is connected to the left side of the connecting block 8, and a top plate 13 is connected to one side of the extension block 9. The top plate 13 limits the second roller 11 to ensure its stable rotation. A rotating rod 14 is connected to the lower part of the top plate 13, and the second roller 11 is connected to the lower part of the rotating rod 14.

[0031] Working principle: In use, firstly, the bolts to be dried are placed above the main body 1 of the device. The conveyor belt above it starts to move the bolts. During the movement, the bolts first come into contact with the second roller 11 and are divided into two piles along the two sides of the second roller 11. At the same time, when they rub against the second roller 11, the second roller 11 rotates through the rotating rod 14 to help spread the bolts out. When they come into contact with the first roller 10, the first roller 10 blocks the stacked bolts, allowing a single bolt to enter the right side and start the drying process.

[0032] As described above, during the drying process, the electric push rod 7 drives the adsorption magnet 5 to descend until the adsorption magnet 5 adheres to the top of the iron filter screen 6. At this time, the adsorption magnet 5 magnetizes the iron filter screen 6, thereby attracting the bolts. When the electric push rod 7 resets, the bolts below the iron filter screen 6 fall freely, and the screen rolls to achieve the flipping operation.

[0033] It should be added that the drying mechanism 2 consists of a front drying chamber, an airflow channel, a blower, and a rear drying chamber. The front and rear drying chambers are equipped with radiators, and the blower is located in the center of the drying mechanism 2. The drying mechanism 2 dries the bolts to ensure the drying process.

[0034] It should be added that the linkage block 4 is symmetrically distributed on both sides of the center of the adsorption magnet 5. The linkage block 4 and the adsorption magnet 5 are installed as a whole. The adsorption magnet 5 and the electric push rod 7 are integrated into a lifting structure. Through the cooperation of the linkage block 4 and the adsorption magnet 5, the adsorption magnet 5 can move up and down to ensure the subsequent bolt flipping work.

[0035] It should be added that the adsorption magnets 5 are evenly and equidistantly distributed above the iron filter screen 6. The iron filter screen 6 is installed as an integral part of the heat insulation cover 3. The width of the iron filter screen 6 is the same as the width of the inner wall of the heat insulation cover 3. The bolt is adsorbed by the iron filter screen 6, and when the adsorption stops, the bolt falls and flips over, thus achieving the purpose of bolt flipping.

[0036] It should be added that side plates 12 are symmetrically distributed on both sides of the extension block 9. The side plates 12 form a rotating structure with the first roller 10 through the rotating rod 14. The extension block 9 and the heat insulation cover 3 are installed as an integral unit. Through the cooperation between the extension block 9 and the side plates 12, the rotating rod 14 can drive the first roller 10 to rotate, so as to flatten the bolts.

[0037] It should be added that the extension blocks 9 are evenly and equidistantly distributed on the left side of the connecting block 8. The extension blocks 9 are connected to the side plate 12 by heat fusion. The side plate 12 forms a rotating structure with the second roller 11 through the rotating rod 14. The bolts are diverted by the cooperation between the side plate 12 and the second roller 11 to avoid the bolts from accumulating in one place.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
